Large Test Cells for ABC Engines
Merford has supplied the largest test cells it has ever built in the Benelux countries for the huge diesel engines manufactured by ABC (Anglo Belgian Corporation) in the Belgian city of Ghent. The test cells consist mostly of concrete, and have removable acoustic wall and roof components. The concrete walls have SKA absorption panels. The test cells also have a ventilation system with silencers and rain hoods. A third test cell will be delivered at the end of 2014.
Largest Test Cells in the Benelux
Merford has constructed two large test cells for Belgium's only engine manufacturer. ABC, in the city of Ghent, was founded 100 years ago and now houses the largest Merford test cells in the Benelux countries. The test cells are used for the long-duration testing of a new generation of diesel engines that comply with the IMO-3 emission standard, and have a capacity of up to 5200 kW and 7065 HP. The engines are 8 metres long, 3 metres wide and 5 metres high.
Access and Ventilation
The test cells are made of concrete with very large openings through which the engines can be lifted in and out. Merford has fitted the test cells with removable acoustic wall and roof components. These large acoustic components can be opened and closed with a bridge crane. Much attention was paid to the safety and stackability of the roof and wall components. Merford has also fitted the two test cells with a ventilation system to discharge the generated heat. Heavy silencers and rain hoods are used for supplying and expelling air.
The hard concrete walls inside the test cells have mechanically strong SKA absorption panels for reducing acoustic reflections in the space. The entire unit has various acoustic doors and acoustic glazing between the testing area and the control room. In the control room, it is almost impossible to hear whether the engine is running or not. ABC has expressed its confidence in Merford and the techniques that have been applied, and a third acoustic test cell is now under construction. It is expected to be operational in late 2014.
